' HOSE AND STAND-PIPE NOZZLE.

SPECIFICATION forming part of Letters Patent No. 688,407, dated December10, 1901.

Application tiled October 8, 1900. Serial No. 32,433. (No model.)

To all whom it may con/cern.-

Beit known that we, JOHN T. GLAZIER and fwhereby a lighter and cheapernozzle is provided and also a more convenient one for portable purposes.Y'

The object is to provide a positive lock to maintain the nozzle in anydesired position when the water-pressure is turned oft' and to simplifyand improve vthe construction in various ways, hereinafter to be fully7described and claimed.

We accomplish the objects of the invention by the mechanism illustratedin the accom-` panying drawings, in which- Figure l is a perspectiveView of our nozzle attached to a hose and showing in dotted lines theuniversal adjustment of the nozzle; Fig. 2, a perspective view of ourinvention attached to a fire-plug; Fig. 3, a' detail in longitudinalsection of our improved nozzle; Fig. 4, an elevation of same looking inthe direction of the arrow, Fig. 3; Fig. 5, a detail in side elevationof a modified construction, and Fig. 6 a second modification 'showingthe supply-pipe passing quite through the head of the nozzle. v

Like letters of reference indicate like parts throughout theseveralviews of the drawings.

A is a sleeve having an interally-threaded end to screw upon acorresponding member of the hose or stand-pipe through which thewater-supply is to be furnished to the nozzle. Above the thread, orinside and adjacent to it rather, is the ilange or, upon which the endof the nozzle-pipe B is seated, and opposite the threadedfend of thesleeve A is the outside ilange a', having a series of bolt-holes. Thepipe B is smaller in diameter than the bore of. the'sleeve A to allowroom for packl pipe by threading the pipe and the ring and screwing thetwo together and then brazing or soldering them to make a solid andpermanent connection. A double pair of bearingrings d d2, making a close[it between the sleeve A and the pipe B, are also slipped upon the endof the pipe B before the ring d is made permanent to the end of the pipeB. The contacting faces of the rings d' and d2 are half-round, which weiind give better results than the ball-bearings provided for in ourformer patent, for the reason that the corrosion of the steel ballscauses them to stick together and bind in the runs. Between the twopairs of bearing-rings are the packingrings d7, of any suit-ableflexible material, which by the pressure of the water against the nozzlewill expand to tighten the joint against leakage. The ring C will bebolted by bolts c to the iange a. It will be seen that rotary movementof the pipe B in the sleeve A is provided for by the construction abovedescribed.'` At a suitable distance above the outside ring C to preventcontact with it the pipe B B is bent nearly at right angles, or quiteso, and at a distance from the pipe approximating its diameter it isgiven a return-bend to provide the member B', which stands at rightangles to the end B, which enters the sleeve A and terminatesapproximately at the continuation of the line passing through thelongitudinal center of said sleeve A.

Mounted on the end of the member B is the head E, which has the inside`sleeve E, large enoughin diameter to receive the end B and permit ofthe insertion of a suitable packing between the end and sleeve. The

sleeve E has an inside flange e, and the end B has an outside flangeb,which contacts with the flange e and regulates the insertion of theend B into the sleeve. The flangeb instead of being formed integral withthe end B in the iirst instance is made separate and internallyscrew-threaded, and after the rings to close the joint are assembled onthe end B the ring b is screwed into place and brazed there.

IOO

F represents any suitable soft packing, and f the gland, which screwsinto the threaded end of the sleeve E. 'The gland has the outsideintegral flange f', which is octagonal in outline to permit of its beingturned with a wrench to screw it in and ont of the sleeve. The head Eturns on the end B' as a pivot, and to prevent the unscrewing of thegland by the turning of the head a ring f2 will be introduced betweenthe gland and the packing. The contacting edges of the gland and ringwill preferably be rounded to reduce the frictional surface as providedfor the rings d and (l2 in the other joint and previously described. Thehead E will have the threaded outlet e', upon which the nozzleg of usualconstruction will be screwed.

By the construction as above described it will be noted that the waterintroduced through the pipe B will be delivered substantially at themiddle of the head E inside of it. The curvature of the wall oppositethe outlet from the end B" deects the stream in a direction opposite tothe outlet through the nozzle, as well as in the direction of the nozzleand also to each side of the nozzle, and the expanded area of the headaround the end B aiords a passage-way around the sides of the end. Thisconstruction, as described and shown, we have found by experience to beessential to the construction of a nozzle in which the back pressure isequalized to an extent which causes it to remain stationary and inert inany given position without being held, as is necessary under heavywater-pressure with the ordinaryslraight nozzle. NVhen thewater-pressure is off, the weight of the nozzlewill cause the head toswing till the nozzle points down, and to hold it up for the sake ofmaking a better appearance or for any other reason while not in use forthrowing water we provide the bracket H from the head E, through whichis a screw-threaded opening to receive the set-screw 7L, which screwsdown against the shoe J, bearing against the end B' of the pipe B. Anydesired pressure or friction of the shoe against the end B can be had byscrewing the setscrew in or out. K represents a like bracket taking fromthe pipe B and having a setscrew Z bearing against the shoe L. The shoeL is pressed against the sleeve A by the setscrew. Neither of the twolocks just described are required. when the water-pressure 1s on.

In the modication shown in Fig. 5 the enlarged head is dispensed with;but such a construction is only applicable to stand-pipes, where a rigidsupport is afforded by the pipe to which the nozzle is attached. Thesenozzles can be pointed to throw a stream in any desired direction in aroom and are specially adapted for use in buildings requiring reprotection and are superior to lilies of hose because of their moredurable nature and also because they can be trained on the fire and leftby themselves to continue to throw water upon the place where set.

In the modification shown in Fig. G the nozzle-head E3 has openingsthrough both of its walls, through which the end B3 of the supply-pipeis passed. The head has annular depressions around the openings aboveinentioned to receive the packing-rings bl. The outer end of the pipe B3is screw-threaded to receive the cap B7, screwing thereon. BG is a metalring between the cap BT and the packing. The pipe has the Harige h5,between which and the head E3 the packing-ring on that side of the headis drawn by the cap on the other side of the head. Water issues from thesupply-pipe through the openingsp in the pipe.

Fig. l shows by the dotted lines the universal adjustment of the nozzleand also shows the purpose of the lugs 71. 71J on opposite sides of thepipe B, which purpose is to support the pipe and keep it on a level withthe expanded head E. The nozzle can be attached directly to thelire-plug in the manner shown in Fig. 2 and trained upon the fire,

where it will remain until reset.

Having thus fully described our invention, what we claim as new, andwish to secure by Letters Patent of the United States, is-

l. The combination, with a sleeve having connection with a water-supplyand a pipe having a turn approximately at right angles and then a doubleor return bend presenting a portion of the pipe approximately at rightangles to the initial part of the pipe, of a head having an insidesleeve reaching to its middle into which said right-angled end of thepipe is inserted, a water-tight packing between the inside sleeve andpipe and a nozzle for the discharge of the water secured to the head,said head being larger in diameter than the inside sleeve and havingcurved walls, substantially as described and shown.

2. The combination, with a sleeve having connection with a water-supplyand a pipe having a turn approximately at right angles and then a doubleor return bend presenting a portion of the pipe approximately at rightangles to the initial part ofthe pipe, of a head having openings throughwhich said rightangled pipe portion is inserted, a water-tight packingbetween the head and pipe and a nozzle for the discharge of the water,secured te the head said head being larger in diameter than the pipe andhaving curved walls, substantially as described and shown.
